Speaking at a foreign policy forum in South Carolina on Tuesday, Gingrich advocated a "commission on gold to look at the whole concept of how do we get back to hard money."
I guess Newt Gingrich has not been reading fellow conservative Ramesh Ponnuru, the mostly right-of-center Market Monetarists, or even libertarian Tyler Cowen. If he had he would know what we need is sound money, not hard money.
P.S. There is no need for a new commission on the gold standard. It has been extensively studied and there is a huge literature on it. I would start with Barry Eichengreen.
